Concepts and Approaches in the Management of Transgender and Gender-Diverse Patients.

The terms transgender and gender diverse (TGD) describe persons whose gender is different from the sex assigned to them at birth. While TGD persons have experienced a rise in cultural and social visibility in recent decades, they continue to experience significant health inequities, including adverse health outcomes and multiple barriers to accessing medical care. Transgender and gender-diverse persons are at a higher risk for pain conditions than their cisgender counterparts, but research on chronic pain management for TGD persons is lacking. Clinicians from all disciplines must be informed of best practices for managing chronic pain in the TGD population. This includes all aspects of care including history, physical examination, diagnosis, treatment, and perioperative management. Many TGD persons report delaying or avoiding care because of negative interactions with medical practitioners who do not have sufficient training in navigating the specific health care needs of TGD patients. Furthermore, TGD persons who do seek care are often forced to educate their practitioners on their specific health care needs. This paper provides an overview of existing knowledge and recommendations for physicians to provide culturally and medically appropriate care for TGD persons.

Histoplasmosis in patients living with HIV in Europe: review of literature.

Histoplasma capsulatum (var. capsulatum Hcc and duboisii Hcd), is a dimorphic fungus that causes histoplasmosis. It usually affects people coming from endemic areas, causing a variety of clinical manifestations up to progressive disseminated histoplasmosis (PDH), especially among people living with HIV (PLWH). We conducted a systematic review to assess histoplasmosis burden of PLWH in Europe. The review follows PRISMA guidelines, with protocol registered in PROSPERO (CRD42023429779). Seventy-eight articles were selected, including 109 patients (32 women). On overall, median age was 37 years. Forty-six patients were Americans, 39 Africans, 17 Europeans, 5 Asians, in 2 cases nationality was not specified. Cases were mainly diagnosed in Italy (28.4%), France (17.3%) and Spain (17.4%), with a north-south gradient. Six cases lacked epidemiologic links with endemic areas. Concerning CDC HIV staging at diagnosis, the information was available for 60 PLWH (55%) and all subjects were at stage C3 except for two subjects at stage B3. PDH was the AIDS-presenting illness in 39 patients. Most patients had a PDH (80.7%); other common extrapulmonary forms were isolated cutaneous histoplasmosis (7.3%), or lymphatic localization (2.7%). In 30 cases, the diagnosis was made by analyzing only one sample. For the remaining 79 cases, multiple samples were collected from each patient. Regarding the biological sample more frequently used for the diagnosis of histoplasmosis, bronchoalveolar lavage sample was taken from 39 patients, and tested positive in 51.3% of cases; 36 patients underwent a skin biopsy which was positive in 86.1% of cases and 28 patients performed bone-marrow biopsy, which led to the diagnosis of histoplasmosis in 92.9% of cases. The identification of Histoplasma capsulatum was available in 97 PLWH through examination of different samples: Hcc and Hcd were identified in 89 and 8 PLWH, respectively. Concerning therapies, 67.9% were treated with liposomal amphotericin B, 18.3% with itraconazole, 10 died pre-treatment. The overall mortality rate was 23.6%. Non-survivors exhibited more frequently gastrointestinal symptoms (p = 0.017), while cutaneous signs correlated with better survival (p = 0.05). Untreated patients faced higher mortality (p < 0.001). Histoplasmosis should be considered amongst opportunistic infection in PLWH, even in Europe, especially if patients originate from or have travelled to endemic areas. Systematic review registration: The registration number is CRD42023429779.

Clinical Impact of Assessment of Myocardial Flow Reserve in Identifying the Cause of Chest Discomfort. / Impacto Clínico da Avaliação da Reserva de Fluxo Miocárdico na Identificação da Causa do Desconforto Torácico.

BACKGROUND: Gamma cameras with cadmium-zinc telluride (CZT) detectors allowed the quantification of myocardial flow reserve (MBF), which can increase the accuracy of myocardial perfusion scintigraphy (MPS) to detect the cause of chest discomfort. OBJECTIVE: To assess the clinical impact of MBF to detect the cause of chest discomfort. METHODS: 171 patients with chest discomfort who underwent coronary angiography or coronary CT angiography also underwent MPS and MBF in a time interval of <30 days. The acquisitions of dynamic imaging of rest and stress were initiated simultaneously with the 99mTc injection sestamibi (10 and 30mCi, respectively), both lasting eleven minutes, followed by immediately acquiring perfusion images for 5 minutes. The stress was performed with dipyridamole. A global or per coronary territory MBF <2.0 was classified as abnormal. RESULTS: The average age was 65.9±10 years (60% female). The anatomical evaluation showed that 115 (67.3%) patients had coronary obstruction significant, with 69 having abnormal MPs and 91 having abnormal MBF (60.0% vs 79.1%, p<0.01). Among patients without obstruction (56 - 32.7%), 7 had abnormal MPS, and 23 had reduced global MBF. Performing MBF identified the etiology of the chest discomfort in 114 patients while MPS identified it in 76 (66.7% vs 44.4%, p<0.001). CONCLUSION: MBF is a quantifiable physiological measure that increases the clinical impact of MPS in detecting the cause of chest discomfort through greater accuracy for detecting obstructive CAD, and it also makes it possible to identify the presence of the microvascular disease.

FUNDAMENTO: Gama-câmaras com detectores de telureto-cádmio-zinco (CZT) permitiram a quantificação da reserva de fluxo miocárdico (RFM), podendo aumentar a acurácia da cintilografia miocárdica de perfusão (CMP) para detectar a causa do desconforto torácico. OBJETIVO: Avaliar o impacto clínico da RFM para detectar a causa do desconforto torácico. MÉTODOS: 171 pacientes com desconforto torácico que foram submetidos a coronariografia ou angiotomografia de coronárias também realizaram CMP e RFM num intervalo de tempo <30 dias. As aquisições das imagens dinâmicas de repouso e estresse foram iniciadas simultaneamente à injeção de 99mTc sestamibi (10 e 30mCi, respectivamente), ambas com duração de onze minutos, seguidas imediatamente pela aquisição das imagens de perfusão durante 5 minutos. O estresse foi realizado com dipiridamol. Uma RFM global ou por território coronariano <2,0 foi classificada como anormal. RESULTADOS: A idade média foi de 65,9±10 anos (60% do sexo feminino). A avaliação anatômica mostrou que 115 (67,3%) pacientes apresentavam obstrução coronariana significativa, sendo que, 69 apresentavam CMP anormal e 91 apresentavam RFM anormal (60,0% vs. 79,1%, p<0,01). Dentre os pacientes sem obstrução (56 ­ 32,7%), 7 tinham CMP anormais e 23 tinham RFM global reduzida. A realização da RFM identificou a etiologia do desconforto torácico em 114 pacientes enquanto a CMP identificou em 76 (66,7% vs. 44,4%, p<0,001). CONCLUSÃO: A RFM é uma medida fisiológica quantificável que aumenta o impacto clínico da CMP na detecção da causa do desconforto torácico através de uma maior acurácia para detecção de DAC obstrutiva e ainda possibilita identificar a presença de doença microvascular.

Use of resources in elderly patients consulting the emergency department: analysis of the Emergency Department and Elder Needs Cohort (EDEN-21).

The elderly population frequently consults the emergency department (ED). This population could have greater use of EDs and hospital health resources. The EDEN cohort of patients aged 65 years or older visiting the ED allowed this association to be investigated. To analyse the association between healthcare resource use and the characteristics of patients over 65 years of age who consult hospital EDs. We performed an analysis of the EDEN cohort, a retrospective, analytical, and multipurpose registry that includes patients over 65 years of age who consulted in 52 Spanish EDs. The impact of age, sex, and characteristics of ageing on the following outcomes was studied: need for hospital admission (primary outcome) and need for observation, stay in the ED > 12 h, prolonged hospital stay > 7 days, need for intensive care unit (ICU) and return to the ED at 30 days related to the index visit (secondary outcomes). The association was analysed by calculating the adjusted odds ratios (aOR) and their 95% confidence intervals (CI), using a logistic regression model. A total of 25,557 patients with a mean age of 78.3 years were analysed, 45% were males. Of note was the presence of comorbidity, a Charlson index ≥ 3 (33%), and polypharmacy (66%). Observation in the ED was required by 26%, 25.4% were admitted to the hospital, and 0.9% were admitted to the ICU. The ED stay was > 12 h in 12.5% and hospital stay > 7 days in 13.5% of cases. There was a progressive increase in healthcare resource use based on age, with an aOR for the need for observation of 2.189 (95% CI 2.038-2.352), ED stay > 12 h 2.136 (95% CI 1.942-2.349) and hospital admission 2.579 (95% CI 2.399-2.772) in the group ≥ 85 years old. Most of the characteristics inherent to ageing (cognitive impairment, falls in the previous 6 months, polypharmacy, functional dependence, and comorbidity) were associated with significant increases in the use of healthcare resources, except for ICU admission, which was less in all the variables studied. Age and the characteristics inherent to ageing are associated with greater use of structural healthcare resources.

DNA damage and repair in patients undergoing myocardial perfusion single-photon emission computed tomography.

As patient exposure to ionizing radiation from medical imaging and its risks are continuing issues, this study aimed to evaluate DNA damage and repair markers after myocardial perfusion single-photon emission computed tomography (MPS). Thirty-two patients undergoing Tc-99m sestamibi MPS were studied. Peripheral blood was collected before radiotracer injection at rest and 60-90 min after injection. The comet assay (single-cell gel electrophoresis) was performed with peripheral blood cells to detect DNA strand breaks. Three descriptors were evaluated: the percentage of DNA in the comet tail, tail length, and tail moment (the product of DNA tail percentage and tail length). Quantitative PCR (qPCR) was performed to evaluate the expression of five genes related to signaling pathways in response to DNA damage and repair (ATM, ATR, BRCA1, CDKN1A, and XPC). Mann-Whitney's test was employed for statistical analysis; p < 0.05 was considered significant. Mean Tc-99m sestamibi dose was 15.1 mCi. After radiotracer injection, comparing post-exposure to pre-exposure samples of each of the 32 patients, no statistically significant differences of the DNA percentage in the tail, tail length or tail moment were found. qPCR revealed increased expression of BRCA1 and XPC, without any significant difference regarding the other genes. No significant increase in DNA strand breaks was detected after a single radiotracer injection for MPS. There was activation of only two repair genes, which may indicate that, in the current patient sample, the effects of ionizing radiation on the DNA were not large enough to trigger intense repair responses, suggesting the absence of significant DNA damage.

Corrected and republished from: "Vibrio fischeri Possesses Xds and Dns Nucleases That Differentially Influence Phosphate Scavenging, Aggregation, Competence, and Symbiotic Colonization of Squid".

Cells of Vibrio fischeri colonize the light organ of Euprymna scolopes, providing the squid bioluminescence in exchange for nutrients and protection. The bacteria encounter DNA-rich mucus throughout their transition to a symbiotic lifestyle, leading us to hypothesize a role for nuclease activity in the colonization process. In support of this, we detected abundant extracellular nuclease activity in growing cells of V. fischeri. To discover the gene(s) responsible for this activity, we screened a V. fischeri transposon mutant library for nuclease-deficient strains. Interestingly, only one strain, whose transposon insertion mapped to nuclease gene VF_1451, showed a complete loss of nuclease activity in our screens. A database search revealed that VF_1451 is homologous to the nuclease-encoding gene xds in Vibrio cholerae. However, V. fischeri strains lacking xds eventually revealed slight nuclease activity on plates upon prolonged incubation. This led us to hypothesize that a second secreted nuclease, identified through a database search as VF_0437, a homolog of V. cholerae dns, might be responsible for the residual nuclease activity. Here, we show that Xds and/or Dns are involved in essential aspects of V. fischeri biology, including natural transformation, aggregation, and phosphate scavenging. Furthermore, strains lacking either nuclease were outcompeted by the wild type for squid colonization. Understanding the specific role of nuclease activity in the squid colonization process represents an intriguing area of future research.IMPORTANCEFrom soil and water to host-associated secretions such as mucus, environments that bacteria inhabit are awash in DNA. Extracellular DNA (eDNA) is a nutritious resource that microbes dedicate significant energy to exploit. Calcium binds eDNA to promote cell-cell aggregation and horizontal gene transfer. eDNA hydrolysis impacts the construction of and dispersal from biofilms. Strategies in which pathogens use nucleases to avoid phagocytosis or disseminate by degrading host secretions are well-documented; significantly less is known about nucleases in mutualistic associations. This study describes the role of nucleases in the mutualism between Vibrio fischeri and its squid host Euprymna scolopes. We find that nuclease activity is an important determinant of colonization in V. fischeri, broadening our understanding of how microbes establish and maintain beneficial associations.

Brain abscess caused by Actinomyces turicensis in a non-immunocompromised adult patient: a case report and systematic review of the literature.

BACKGROUND: Actinomyces turicensis is rarely responsible of clinically relevant infections in human. Infection is often misdiagnosed as malignancy, tuberculosis, or nocardiosis, therefore delaying the correct identification and treatment. Here we report a case of a 55-year-old immunocompetent adult with brain abscess caused by A. turicensis. A systematic review of A. turicensis infections was performed. METHODS: A systematic review of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The databases MEDLINE, Embase, Web of Science, CINAHL, Clinicaltrials.gov and Canadian Agency for Drugs and Technology in Health (CADTH) were searched for all relevant literature. RESULTS: Search identified 47 eligible records, for a total of 67 patients. A. turicensis infection was most frequently reported in the anogenital area (n = 21), causing acute bacterial skin and skin structure infections (ABSSSI) including Fournier's gangrene (n = 12), pulmonary infections (n = 8), gynecological infections (n = 6), cervicofacial district infections (n = 5), intrabdominal or breast infections (n = 8), urinary tract infections (n = 3), vertebral column infections (n = 2) central nervous system infections (n = 2), endocarditis (n = 1). Infections were mostly presenting as abscesses (n = 36), with or without concomitant bacteremia (n = 7). Fever and local signs of inflammation were present in over 60% of the cases. Treatment usually involved surgical drainage followed by antibiotic therapy (n = 51). Antimicrobial treatments most frequently included amoxicillin (+clavulanate), ampicillin/sulbactam, metronidazole or cephalosporins. Eighty-nine percent of the patients underwent a full recovery. Two fatal cases were reported. CONCLUSIONS: To the best of our knowledge, we hereby present the first case of a brain abscess caused by A. turicensis and P. mirabilis. Brain involvement by A. turicensis is rare and may result from hematogenous spread or by dissemination of a contiguous infection. The infection might be difficult to diagnose and therefore treatment may be delayed. Nevertheless, the pathogen is often readily treatable. Diagnosis of actinomycosis is challenging and requires prompt microbiological identification. Surgical excision and drainage and antibiotic treatment usually allow for full recovery.

Sex- and age-related patterns in the use of analgesics in older patients in the emergency department.

BACKGROUND: Treatment of acute pain in older patients is a common challenge faced in emergency departments (EDs). Despite many studies that have investigated chronic analgesic use in the elderly, data on patterns of acute use, especially in EDs, of analgesics according to patient characteristics is scarce. OBJECTIVE: To investigate sex- and age-related patterns of analgesic use in the Spanish EDs and determine differences in age-related patterns according to patient sex. DESIGN: A secondary analysis of the Emergency Department and Elderly Needs (EDEN) multipurpose cohort. SETTING: Fifty-two Spanish EDs (17% of Spanish EDs covering 25% of Spanish population). PARTICIPANTS: All patients' ≥65 years attending ED during 1 week (April 1-7, 2019). Patient characteristics recorded included age, sex, chronic treatment with non-steroidal anti-inflammatory drugs (NSAIDs) and opiates, comorbidity, dependence, dementia, depression, ability to walk and previous falls. Analgesics used in the ED were categorized in three groups: non-NSAID non-opioids (mainly paracetamol and metamizole, PM), NSAIDs, and opiates. OUTCOME MEASURES: Frequency of analgesic use was quantified, and the relationship between sex and age and analgesic use (in general and for each analgesic group) was assessed by unadjusted and adjusted logistic regression and restricted cubic spline models. Interaction between sex and age was explored. MAIN RESULTS: We included 24 573 patients, and 6678 (27.2%) received analgesics in the ED: 5551 (22.6%) PM, 1661 (6.8%) NSAIDs and 937 (3.8%) opiates (1312 received combinations). Analgesics were more frequently used in women (adjusted OR = 1.076, 95%CI = 1.014-1.142), as well as with NSAID (1.205, 1.083-1.341). Analgesic use increased with age, increasing PM and decreasing NSAIDs use. Opiate use remained quite constant across age and sex. Interaction of sex with age was present for the use of analgesics in general ( P  = 0.006), for PM ( P  < 0.001) and for opiates ( P  = 0.033), with higher use of all these analgesics in women. CONCLUSION: Use of analgesics in older individuals in EDs is mildly augmented in women and increases with age, with PM use increasing and NSAIDs decreasing with age. Conversely, opiate use is quite constant according to sex and age. Age-related patterns differ according to sex, with age-related curves of women showing higher probabilities than those of men to receive any analgesic, PM or opiates.

Hyperactive delirium during emergency department stay: analysis of risk factors and association with short-term outcomes.

To investigate factors related to the development of hyperactive delirium in patients during emergency department (ED) stay and the association with short-term outcomes. A secondary analysis of the EDEN (Emergency Department and Elderly Needs) multipurpose multicenter cohort was performed. Patients older than 65 years arriving to the ED in a calm state and who developed confusion and/or psychomotor agitation requiring intravenous/intramuscular treatment during their stay in ED were assigned to delirium group. Patients with psychiatric and epileptic disorders and intracranial hemorrhage were excluded. Thirty-four variables were compared in both groups and outcomes were adjusted for age, sex, Charlson Comorbidity Index, Barthel Index and polypharmacy. Hyperactive delirium that needed treatment were developed in 301 out of 18,730 patients (1.6%). Delirium was directly associated with previous episodes of delirium (OR: 2.44, 95% CI 1.24-4.82), transfer to the ED observation unit (1.62, 1.23-2.15), chronic treatment with opiates (1.51, 1.09-2.09) and length of ED stay longer than 12 h (1.41, 1.02-1.97) and was indirectly associated with chronic kidney disease (0.60, 0.37-0.97). The 30-day all-cause mortality was 4.0% in delirium group and 2.9% in non-delirium group (OR: 1.52, 95% CI 0.83-2.78), need for hospitalization 25.6% and 25% (1.09, 0.83-1.43), in-hospital mortality 16.4% and 7.3% (2.32, 1.24-4.35), prolonged hospitalization 54.5% and 48.6% (1.27, 0.80-2.00), respectively, and 90-day post-discharge combined adverse event 36.4% and 35.8%, respectively (1.06, 0.82-2.00). Patients with previous episodes of delirium, treatment with opioids and longer stay in ED more frequently develop delirium during ED stay and preventive measures should be taken to minimize the incidence. Delirium is associated with in-hospital mortality during the index event.

Older Adult Patients in the Emergency Department: Which Patients should be Selected for a Different Approach?

BACKGROUND: While multidimensional and interdisciplinary assessment of older adult patients improves their short-term outcomes after evaluation in the emergency department (ED), this assessment is time-consuming and ill-suited for the busy environment. Thus, identifying patients who will benefit from this strategy is challenging. Therefore, this study aimed to identify older adult patients suitable for a different ED approach as well as independent variables associated with poor short-term clinical outcomes. METHODS: We included all patients ≥65 years attending 52 EDs in Spain over 7 days. Sociodemographic, comorbidity, and baseline functional status data were collected. The outcomes were 30-day mortality, re-presentation, hospital readmission, and the composite of all outcomes. RESULTS: During the study among 96,014 patients evaluated in the ED, we included 23,338 patients ≥65 years-mean age, 78.4±8.1 years; 12,626 (54.1%) women. During follow-up, 5,776 patients (24.75%) had poor outcomes after evaluation in the ED: 1,140 (4.88%) died, 4,640 (20.51) returned to the ED, and 1,739 (7.69%) were readmitted 30 days after discharge following the index visit. A model including male sex, age ≥75 years, arrival by ambulance, Charlson Comorbidity Index ≥3, and functional impairment had a C-index of 0.81 (95% confidence interval, 0.80-0.82) for 30-day mortality. CONCLUSION: Male sex, age ≥75 years, arrival by ambulance, functional impairment, or severe comorbidity are features of patients who could benefit from approaches in the ED different from the common triage to improve the poor short-term outcomes of this population.

[Impacto de la dependencia funcional de los pacientes mayores atendidos en los servicios de Urgencias españoles durante la primera ola pandémica de la COVID-19 sobre la mortalidad a 30, 180 y 365 días en función del diagnóstico (COVID versus no COVID).] / Impact of functional dependency of elderly patients seen in Spanish emergency departments during the first wave of the COVID-19 pandemic on mortality at 30, 180 and 365 days depending on the diagnosis (COVID versus non-COVID).

OBJECTIVE: Functional assessment is part of geriatric assessment. How it is performed in hospital Emergency Departments (ED) is poorly understood, let alone its prognostic value. The aim of this paper was to investigate whether baseline disability to perform basic activities of daily living (BADL) was an independent prognostic factor for death after the index visit to the ED during the first wave of the COVID-19 pandemic and whether it had a different impact on patients with and without diagnosis of COVID-19. METHODS: A retrospective observational study of the EDEN-Covid (Emergency Department and Elder Needs during COVID) cohort was carried out, consisting of all patients aged ≥65 years seen in 52 Spanish EDs selected by chance during 7 consecutive days (30/3/2020 to 5/4/2020). Demographic, clinical, functional, mental and social variables were analyzed. Dependence was categorized with the Barthel index (BI) as independent (BI=100), mild-moderate dependence (100>BI>60) and severe-total dependence (BI<60), and their crude and adjusted association was evaluated with mortality at 30, 180 and 365 days using COX proportional hazards models. RESULTS: Of 9,770 enrolled patients with a mean age of 79 years, 51% were men, 6,305 (64.53%) were independent, 2,340 (24%) had mild-moderate dependence, and 1,125 (11.5%) severe-total dependence. The number of deaths at 30 days in these three groups was 500 (7.9%), 521 (22.3%) and 378 (33.6%), respectively; at 180 days it was 757 (12%), 725 (30.9%) and 526 (46.8%); and at 365 days 954 (15.1%), 891 (38.1%) and 611 (54.3%). In relation to independent patients, the adjusted risks (hazard ratio) of dying within 30 days associated with mild-moderate and severe-total dependency were 1.91 (95% CI: 1.66-2.19) and 2.51. (2.11-2.98); at 180 days they were 1.88 (1.68-2.11) and 2.64 (2.28-3.05); and at 365 days they were 1.82 (1.64-2.02) and 2.47 (2.17-2.82). This negative impact of dependency on mortality was greater in patients diagnosed with COVID-19 than in non-COVID-19 (p interaction at 30, 180 and 365 days of 0.36, 0.05 and 0.04). CONCLUSIONS: The functional dependence of older patients who attend Spanish EDs during the first wave of the pandemic is associated with mortality at 30, 180 and 365 days, and this risk is significantly higher in patients treated for COVID-19.

OBJETIVO: La valoración funcional forma parte de la valoración geriátrica. No se conoce bien cómo se realiza en los servicios de Urgencias hospitalarios (SUH) y menos aún su valor pronóstico. El objetivo de este trabajo fue investigar si la dependencia funcional basal para realizar las actividades básicas de la vida diaria (ABVD) era un factor pronóstico independiente de muerte tras la visita índice al SUH durante la primera ola pandémica de la COVID-19 y si tuvo un impacto diferente en pacientes con y sin diagnóstico de COVID-19. METODOS: Se realizó un estudio observacional retrospectivo de la cohorte EDEN-Covid (Emergency Department and Elder Needs during COVID) formada por todos los pacientes de edad mayor o igual a 65 años atendidos en 52 SUH españoles, seleccionados por oportunidad durante siete días consecutivos (del 30 de marzo al 5 de abril de 2020). Se analizaron variables demográficas, clínicas, funcionales, mentales y sociales. La dependencia se categorizó con el índice de Barthel (IB) en independiente (IB=100), dependencia leve-moderada (100>IB>60) y dependencia grave-total (IB<60), y se evaluó su asociación cruda y ajustada con la mortalidad a 30, 180 y 365 días mediante modelos de riesgos proporcionales de COX. RESULTADOS: De 9.770 pacientes incluidos con una media de edad de 79 años, un 51% eran hombres, 6.305 (64,53%) eran independientes, 2.340 (24%) tenían dependencia leve-moderada y 1.125 (11,5%) dependencia grave-total. El número de fallecidos a 30 días en estos tres grupos fue 500 (7,9%), 521 (22,3%) y 378 (33,6%), respectivamente; a 180 días fue 757 (12%), 725 (30,9%) y 526 (46,8%); y a 365 días 954 (15,1%), 891 (38,1%) y 611 (54,3%). En relación a los pacientes independientes, los riesgos (hazard ratio) ajustados de fallecer a 30 días, asociados a dependencia leve-moderada y grave-total, fueron 1,91 (IC 95%: 1,66-2,19) y 2,51 (2,11-2,98); a 180 días fueron de 1,88 (1,68-2,11) y 2,64 (2,28-3,05); y a 365 días fueron 1,82 (1,64-2,02) y 2,47 (2,17-2,82). Este impacto negativo de la dependencia sobre la mortalidad fue mayor en pacientes diagnosticados de COVID-19 que en los no COVID-19 (p interacción a 30, 180 y 365 días de 0,36, 0,05 y 0,04). CONCLUSIONES: La dependencia funcional de los pacientes mayores que acuden a SUH españoles durante la primera ola pandémica se asocia a mortalidad a 30, 180 y 365 días, y este riesgo es significativamente mayor en los pacientes atendidos por COVID-19.

Time-Restricted Eating and Its Metabolic Benefits.

Newer management strategies are being evaluated to treat obesity, which continues to increase worldwide. After 12 h of fasting, the body switches from glucose to fat metabolism, regulating protein synthesis and autophagy. These cellular responses are central to the metabolic benefits of time-restricted eating (TRE), independent of calorie restriction and weight loss, and they have heightened interest in TRE regimens. Controversy remains, however, regarding the benefits of TRE regimens. We reviewed the current literature and concluded that TRE is equivalent to calorie restriction for weight loss and has positive effects for patients with diseases such as nonalcoholic fatty liver disease, cancer, and cardiovascular disease.

Daptomycin-induced eosinophilic pneumonia: a case report and systematic review.

Introduction Acute eosinophilic pneumonia (AEP) is a rare respiratory condition caused by eosinophil accumulation in the pulmonary tissue that can be related to drug administration. Daptomycin, an antibiotic active against gram-positive bacteria, is one of the leading causes of AEP among drugs. In order to raise awareness of this rare syndrome, in our work we have described a case of an 82 years-old male with Enterococcus faecalis endocarditis treated with daptomycin, who developed a daptomycin-induced AEP. We have performed a systematic review of the literature for all similar reported cases. Methods The systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. To conduct the analysis, the terms "daptomycin AND eosinoph* AND pneum*", were entered the databases Medline, Cinahl and Embase on April 13th, 2023. We considered relevant all records documenting AEP after daptomycin use. No restrictions in terms of year or language were made. A formal appraisal of observational studies was performed by Newcastle-Ottawa Scale. All results and data were reported by means of tables. Results Our search identified 93 relevant records, published between 2007 and 2023. A total of 120 patients were considered. Patients who experienced AEP were mostly males (n=88, 73.3%) with a mean age of 68.28 years (SD11.54). Daptomycin was most frequently prescribed for osteoarticular infections (n=75, 62.5%) and to treat gram-positive cocci infections. The most frequently isolated pathogen was Methicillin-resistant Staphylococcus aureus (MRSA). Daptomycin was mostly used with off-label indications (n=89, 74%). Symptoms of AEP were usually reported after a mean of 21.75 days of treatment (range 3-84) and typically included fever, dyspnea, dry cough and acute respiratory failure. Reported treatment strategies invariably included daptomycin withdrawal, respiratory support, and corticosteroid treatment. One hundred and sixteen patients fully recovered. A fatal outcome was described in 4 patients. Suggestive symptoms and imaging raised suspicion for AEP, confirmed with bronchoalveolar lavage in 57.5% of the cases. Discussion and Conclusions Daptomycin-induced AEP is a rare but potentially fatal complication, mostly reported after long treatment with daptomycin. Clinicians should be aware of this syndrome, as it could be initially misdiagnosed for an acute infectious respiratory syndrome, resulting in a delay in its diagnosis and treatment. Furthermore, since the risk of developing AEP is increased by longer drug exposure, caution should be used when discussing the use of daptomycin in longer treatment regimens.

Therapeutic Challenges for Gastric Neuroendocrine Neoplasms: Take It or Leave It?

Background and Objectives: Gastric neuroendocrine neoplasms (gNENs) represent rare but increasingly recognized tumors. They are distinguished into three main clinical types (type-1, type-2, and type-3) according to gastrin level and at histological evaluation in well-differentiated G1, G2, or G3 lesions, as well as poorly-differentiated lesions. Small type-1 and type-2 neoplasms with low proliferation indices demonstrated excellent survival without progression during an extended follow-up period, and for these reasons, active endoscopic observation or endoscopic resection are feasible options. On the other hand, surgery is the treatment of choice for more aggressive type-3, G3, or infiltrating neoplasms. The present study aims to comprehensively review and compare the available therapeutic strategies for gNENs. Materials and Methods: A computerized literature search was performed using relevant keywords to identify all of the pertinent articles with particular attention to gNEN endoscopic treatment. Results: In recent years, different endoscopic resective techniques (such as endoscopic mucosal dissection, modified endoscopic mucosal resection, and endoscopic full-thickness resection) have been developed, showing a high rate of complete resection for advanced and more aggressive lesions. Conclusions: Overall, gNENs represent a heterogeneous group of lesions with varying behavior which require personalized management. The non-operative approach for small type-1 gNENs seems to be feasible and should be promoted. A step-up approach with minimally invasive endoscopic therapies might be proposed, particularly for type-1 gNEN. On the other hand, it is important to recognize the negative prognostic factors in order to identify those rare cases requiring more aggressive approaches. A possible therapeutic algorithm for localized gNEN management is provided.

The Impact of Viral and Bacterial Co-Infections and Home Antibiotic Treatment in SARS-CoV-2 Hospitalized Patients at the Policlinico Tor Vergata Hospital, Rome, Italy.

Co-infections during COVID-19 may worsen patients' outcomes. This study reports the results of a screening assessing the presence of co-infections among patients hospitalized for SARS-CoV-2 infection in the Infectious Diseases-Ward of the Policlinico Tor Vergata Hospital, Rome, Italy, from 1 January to 31 December 2021. Data on hepatitis B and C virus, urinary antigens for legionella pneumophila and streptococcus pneumoniae, pharyngeal swab for respiratory viruses, QuantiFERON®-TB Gold Plus assay (QFT-P), blood cultures and pre-hospitalization antibiotic prescription were recorded. A total of 482 patients were included, 61% males, median age of 65 years (IQR 52-77), median Charlson comorbidity index of 4 (IQR 2-5). The mortality rate was 12.4%; 366 patients needed oxygen supply. In total, 151 patients (31.3%) received home antibiotics without any association with the outcome. No significant association between mortality and the positivity of viral hepatitis markers was found. Out of 442 patients, 125 had an indeterminate QFT-P, associated with increased mortality. SARS-CoV-2 was the only respiratory virus detected among 389 pharyngeal swabs; 15/428 patients were positive for S. pneumoniae; none for L. pneumophila. In total, 237 blood cultures were drawn within 48 h from hospital admission: 28 were positive and associated with increased mortality. In our cohort, bacterial and viral co-infections in COVID-19 hospitalized patients were rare and not associated with higher mortality.

Incidence and prevalence of gastric neuroendocrine tumors in patients with chronic atrophic autoimmune gastritis.

BACKGROUND: The incidence of type I gastric neuroendocrine neoplasms (gNENs) has increased significantly over the past 50 years. Although autoimmune gastritis (AIG) increases the likelihood of developing gNENs, the exact incidence and prevalence of this association remain unclear. AIM: To evaluate the incidence and prevalence of type I gNENs in a cohort of patients with a histological diagnosis of AIG. METHODS: Patients with a histological diagnosis of AIG were enrolled between October 2020 and May 2022. Circulating levels of CgA and gastrin were assessed at enrollment. Included patients underwent regular endoscopic follow-up to detect gastric neoplastic lesions, enterochromaffin-like (ECL) cell hyperplasia, and the development of gNEN. RESULTS: We included 176 patients [142 women (80.7%), median age 64 years, interquartile range (IQR) 53-71 years] diagnosed with AIG between January 1990 and June 2022. At enrollment. One hundred and sixteen patients (65.9%) had ECL hyperplasia, of whom, 29.5% had simple/linear, 30.7% had micronodular, and 5.7% had macronodular type. The median follow-up time was 5 (3-7.5) years. After 1032 person-years, 33 patients developed a total of 50 type I gNENs, with an incidence rate of 0.057 person-years, corresponding to an annual cumulative incidence of 5.7%. Circulating CgA levels did not significantly differ between AIG patients who developed gNENs and those who did not. Conversely, gastrin levels were significantly higher in AIG patients who developed gNENs [median 992 pg/mL IQR = 449-1500 vs 688 pg/mL IQR = 423-1200, P = 0.03]. Calculated gastrin sensitivity and specificity were 90.9% and 1.4%, respectively, with an overall diagnostic accuracy of 30% and a calculated area under the gastrin receiver operating characteristic curve (AUROC or AUC) of 0.53. CONCLUSION: Type I gNENs are a significant complication in AIG. Gastrin's low diagnostic accuracy prevents it from serving as a marker for early diagnosis. Effective strategies for early detection and treatment are needed.
